The Schedule referred zo in these Letters Patent and making peut: o the same.

To all persons lo what# these presents may com r.-

Be itknown that; I, IOSEPII F. BALDwxX, ot'lrovincetown, in the county of Barnstable, and State of' Massachusetts, have mode' anew and nset'nl invention, having reference to the Preservation ot' Vegetable or Animal Matters on shipboard; and l do hereby de-V chire the sntne to he fully described in the tbllowing specification, and rep'esented in the accompanying drawings, of which- Figure 1 denotes a vertical and transverse section of the hull of a navigable vessel, as provided with my invention.

The object- I have had in view, in making such invention, has been to soeonstrnct. a navigable vessel :is to render il, very advaulageously capable of preserving from decay, during a voyage, fruits, vegetables, or vnx'ions other articles of a perishable nnture.

In carrying out my invention, I creci: within the main deck, A, and poop, 1, ofthe vessel, one or more horn above anu below the neon, und nearly up to the poop-doek C, such chamber, or chambers, being intended for receiving and holding,r ice in blocks.

In the sides oi that part. of each of the said icere-y These chambers, or cargo-receptaclcs, are arranged beneath the deck l?, and separated from one another by an air-space, E, disposed between and extending from top to bottom of them, in manner as repre sented.

Furthermore, there is another nhbspace, F, arranged underneath the bottom and against the outer side of each cargmeceptaele, such space being extended nearly np to the maindeck, and made to open into the airspace S, between the main and auxiliary decks A and b.

At'. each side of the auxiliary deck, I form a gutter, or channel, H, to receive the wnterthal: may ilow from the. ice-xeceptaclc, and be disch-.urged on the auxiliary deck.

This deck should slope from its middle to nach of the gutters, which may discharge the writer through scnppers, 0r into one or more cisterne or tanks.

Below the air-space, underneath the cargo-receiving chambers I) D, 1 arrange, across the hull, a, cement Noten-tight Hooi-ing, Land have below it a. space, K,'

for holding ballast..

The ice-room, or receptacle, where it extends above. the main deck, should have suitable heat non-conf ducting covering, orbe so constructed that the hea-t of the air which may be within. the space around it may not; be readily conducted to the ice.

1t is intended for the cargo-receptacles to be made of sheet-iron galvanized, or, in otlierwonls, protected by coatings oi' zinc, or other material or composition not readily oxidiznble.

There should be suitable hatchways, or openings into sui-h receptacles, for the purpose of getting cargo into :1nd l'rinn them, such hatehwatvs being provided with proper hatches, n' covers.

The saine may be said with respect to the icechnniber.

When o. vessel is constructed as o'oove specified, the ice-receptacle duly charged with ice, and the cargocbninbcrs are supplied with frnit,or vegetable, or :ininnil-niatteis, which, h; being kept in o cool shite, will be preserved from deny or decomposition, it will be seen that the air in the space S, between the inner and zmxilznjdccks, will be cooled by cont-.ict with the ice, and will poss into the spaces about and between the cargo-elunnbers, aid thus will cool their sides, and

by obstructing. the bent, 1t' ihoaixwwhioh may be within such receptacle, will lieep their contents at a low temperature, or one which will protect them from decay.

The air-spaces next the sides and bottom ol' the cargo-receptacles, also, so insulate them from the sides of the hull :is to prevent thebeat of the hnll, or the waiter in which itJ may fion-t, from being absorbed by the walls ofthe clnuobers.

The water-tight tiooring prevents any water which may leali into the ballast-hold, or splice, from coming in Contact with the floors ofthe cargo-chainbers.

l contemplate using), a. quantity of qniclolinie or other proper absorbent in each ot' the cnrgo-coni1nirt ments, such bving'to absorb any moisture which muy be gein-rated therein, by reason of .vhnt is termed the sweating ot the fruit.

The employment; ot' o poop over the icc-receptacle, protects it from the lays ofthe sun, and the power ot' such to lient it, and thereby melt the ice.

I olaini as my invention the llillowing, viz:

The hereiu-described arrangements nl the moin deel; :1nd hull and the ice-receptacle, with the cargo-receptacles and the air-spaces between and nbont che cargoreceptacles.

Also, the arrangement. of the water-iight flooring l; weeeptncle in the hull, with the cargo l s ond air-spaces disposed together,

and the bnl and ice-reeel und with respect to the mein (leek and hull, in manner substantially es not forth.

Also, the combination and arrangement of the poop I), with the main deck, the ice and cargwreeepecles,

and their air-spaces disposed together and within the hull, substantially 9,3 specified.
